The French flu is also a subtype of Influenza A, but is different to Aussie flu.

Pharmacist and Jakemans expert Marvin Munzu said: The French flu is another strain of the deadly flu virus, similar to the Aussie flu.”

The French Ministry of Health has warned that the flu epidemic will continue to spread across France.

Chronic cough: A cough that you have had for a month or longer is considered chronic. This is an important early symptom that tells you something is wrong with your respiratory system.

It is expected that French flu will make its way to the UK, after it has already reached “epidemic levels”.

The symptoms of French flu are similar to those of Aussie flu, however, according to Munzu, the viral infection can be spread by people that don’t know they have the virus.

He says the people most at risk from the deadly virus are children, the elderly, pregnant women and people with underlying health conditions.

The French Ministry of Health said: “The influenza epidemic is of an exceptional magnitude, by the number of cases, which risks exceeding those of the last two years.”

Malaria: Between 350 to 500 million cases of malaria are diagnosed each year in sub-Saharan Africa, though fortunately there is a good survival rate

Japanese flu

Japanese flu is – contrary to Aussie flu – of the category Influenza B.

This type of flu is said to be more contagious than Aussie flu, and children are especially susceptible to it.

A PHE spokeswoman said: “Japanese flu is a B strain of flu, so less aggressive than Aussie flu or swine flu, which are both A strains. But, while the symptoms are likely to be less severe, it can spread faster.

Experts say that this is because children are considered “super shredders”, meaning their immune systems shoot off more of the virus because their immune systems can’t distinguish between what will make them ill and what will kill them.
